ROLLER-BEARIKG.

Specification of Letters Patent.

Application filed Febrhary 19, 1915. Serial N eerie To all whomit yconcern:

Be it known that I, Gn AnLns S. Loom WOGD, a citizen of the UnitedS.tates, residing at 289 Market street, Newark, county of Essex, andState of'New Jersey, have invented certain new and useful Improve? mentsin Roller-l3earings, fully described and represented in the followingspecification and the accompanying drawings, forming' a part of thesame.

'lhis invention relates to a roller-bearing having a conical hub until aset of corneal rollers fitted thereto, and a casing having a to .ieringseat adapted to bear upon the outer si .es of the rollers; and theobject of the invention is to provide a novel and eflicient means ofresisting the end thrust which is caused in bearings having taperingroll ere, when subjected either to lateral or longitudinal strain. Thisobject is attained by forming each roller with a collar upon.

one end and forming a shoulder upon the outer casing adapted to engagesuch collar upon either its inner or outer side; the shoulder beingprojected inwardly beyond the line of the roll-seat so that the line ofcontact between the collar and shoulder shall extend equally inside andoutside the line of the roll-sent Where the hearing between the shoulderand the collar is upon the inner side of the collar, the roll isnecessarily necked at such point to clear the shoulder which projectsinwardly beyond such line of the roll-scat,

but where the shoulder contacts with the outer side of the collar, suchnecking is not necessary.

In practice, a cage is used to hold the set of rollers in their workingposition in the casing, and any device for resisting end thrust whichtends to tip the rollers in the cage produces a frictional contact andwear, wh ch is very in urious.

l Vith the present construction, the contact of the roll-collar with theshoulder upon the casing prodlices as great a tendency to accelerate asit does to retard the end of the roller which carries the collar, andsuch tendencies therefore neutralize or Fig. 2 is an. edge view of thehuh for such bearing; Fig. 3 is a section of the hub, cesing, androller, greatly enlarged; Fig. 4 is van edge view, partly in sectionwhere hatched, of a bearing having a double coni- "he inner side thecollar 1S shown proviced'with n. tiered or beveled seat e, which njlakesthe collar provided witl s l'vxlsides of the rollers. an annular shonl--dcr 9 formed at a suitable angle with the roll-scat f to lit the novel(.1 imon the collar (1, thus making a. line cont-dot tl'ierewith. Theshoulder is formed so the neck (Z of the collar and thus crosses theline 8, s, of the roll-seat, the parts being so proportioned that thehearing of seat 6 and the shoulder 51 extends in rally inside andoutside the line 5, s. so 3% .t while one would produce a. rcta'" ngz;tendency upon the smaller and oi thir I the ends of th casing, and hring collars d engaging seats upon the c: 5 construction shown in 1 Asthe larger ends oi ollcrs lie in the interior of the casing, it heimpossihle til-assemble the parts without dii'idi the casing at themiddle of its l: :-.;*gth, as shown at the line :i in his oasis as withthe M Such parts are formed with relihet r on their 0 corners, so thatwhen oil the parts of the casing arc'asscmbled a shell may he fittedover the casing-parts and Flanged by spin-- ning into the said rahoets,as shown in the drawing.

In Fig. 6, the collar larger end oi the roll corner 0' upon its outermth the beveled to project into- .dc, and the casing is formed with agroove f, to clear the margin of such collar, and with an annularshoulder 9' adjacent to such groove and end, and a casing fitted to theexterior of the rolls and provided with a shoulder to engage suchcollar, and the contact between the roller and the shoulder extendingequally inside and 'outside'the line of the roll-seat in the casing.

2. A roller bearing having a conical hub, aset of tapering rollersfitted to such hub and provided each With a collar upon one end beveledupon one side, and a casing fitted to the exterior of the rollers andprovided with a shoulder adapted to make a line contact with the beveledsurface of the collar, and such contact extending equally inside andoutside the line of the roll-seat in the casing.

3. A roller bearing having a conical hub,

roll-seat. 4

4. In a roller bearing for sustaining latoral and end thrusts, thecombination, with a hub tapered in both directions from the middle ofits length, of two setsof tapering rollers'titted to the hub andprovided each 4 with a collar upon its outer end and a neck adjacent tosuch .collar, a casing formed in two parts each having a tapering seatfitted to one series of the rollers and havinga shoulder projecting'intothe said necks and 5 contacting); with the inner sides of the saidcollars, the shoulders thus making a line contact with the collarsequally inside and i outside the line of the said seat.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
